PIL Image im.show() no show!

[Pedroski55]

For my little OMR programme, I need to crop the image I have into columns. Normally this works no problem.

The image is an A4 size .jpg. The 'bubbles' for each question are in rows and, in this case, 2 columns.

I have done this many many times. I keep entering coordinates for cropping, top left, bottom right, until I get what I want, then save the crop-coordinates.

Today something weird is wrong.

I load an image in /home/pedro/summer2022/OMR/20BE/pdf2jpg/20BE11.jpg to get the crop coordinates.

from PIL import Image, ImageOps
image = '/home/pedro/summer2022/OMR/20BE/pdf2jpg/20BE11.jpg'

Image opens the jpg, and im is the correct size, A4

>>> im = Image.open(image)
>>> im
<PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1654x2339 at 0x7FB3AA6ABA30>

but when I try im.show()

>>> im.show()

I get "No images found in "file:///tmp/tmpw6yxazsp.PNG" (I can't see how to post the screenshot of the image of the output window, but that's what it says.)

This has always worked without a hitch!

Any clues as to what may be wrong? I guess an update changed something. A permissions thing??

I tried another Python programme I have to make little 5 question answer forms. Same problem, can't get the coordinates. Has always worked.
